Title: Luminous spectral analyzing method on photoelectric photometry system
Inventor: OCHIAI TAKASHI
IPC: G01J1/44
Filed: 1979-03-13
Abstract: PURPOSE:To make it possible to analyze accurately the content rate of an element component in a metal solid-state sample by removing an abnormally-intense luminous pulse appearing among stable intense luminous pulses by adding the special waveform process to the output signal of a photo electron multipler tube. CONSTITUTION:The crest value of each pulse of the output signal of a photoelectron multiplier tube is found, the fixed level width is found from the mean value of the above-mentioned pulse crest values of random level width; and following pulse crest values residing within the level range are averaged to renew the fixed level width, and pulse crest values within this level range are integrated to obtain a quantitative value. For example, the maximum value of each luminous pulse of the output signal of the photoelectron multipler tube is held by peak holding circuit 1, whose output signal is inputted to sample holding circuit 2. Then, the output signal of circuit 2 is averaged by low-pass filter 4 and a voltage obtained by giving the signal adequate width is compared with the output voltage of circuit 1, so that a decision on whether the signal having been inputted to circuit 2 is abnormal or normal.

Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration in the visual sensation characteristics of a screen, each as reversal development at a vertical visual field angle, by determining the min. wavelength λ among the wavelengths of the light relating to colors, the min. value V1 of a driving voltage and the optical phase difference R(V1 ) at this voltage so as to satisfy a specific relation. SOLUTION: The optimum value of the optical phase difference R(V1 ) relating to the respective colors of R(red), G(green), B(blue) is determined, by which the optically rotatory power of liquid crystals for B(blue) wavelength is prevented. The R(V1 ) is the absolute value of retardation before correction by a phase compensation film at the driving voltage V. on a low side. Namely, the occurrence of the optically rotatory power of the liquid crystals for the B(blue) wavelength is prevented by the optimization of the value of R(V1 )/λ. The term 'optimization' signifies to satisfy the relation R(V1 )/λ=<0.85 for the B(blue) wavelength. The reason thereof is that only the wavelength of B(blue) among three color light rays to be used for the liquid crystal display is relatively apart as compared with the wavelength of R(red), G(green).
